Abstract
BACKGROUND Paediatric thoracolumbar spine injuries are rare, and meaningful epidemiological data are lacking. OBJECTIVES The aim of this study was to provide epidemiological data for paediatric patients with thoracolumbar spinal trauma in Germany with a view to enhancing future decision-making in relation to the diagnostics and treatment of these patients. MATERIALS AND METHODS A retrospective multicentre study includes patients up to 16 years of age who were suffering from thoracolumbar spine injuries who had been treated in six German spine centres between 01/2010 and 12/2016. The clinical database was analysed for patient-specific data, trauma mechanisms, level of injury, and any accompanying injuries. Diagnostic imaging and subsequent treatment were investigated. Patients were divided into three age groups for further evaluation: age group I (0-6 years), age group II (7-9 years) and age group III (10-16 years). RESULTS A total of 153 children with 345 thoracolumbar spine injuries met the inclusion criteria. The mean age at the time of hospitalization due to the injury was 12.9 (± 3.1) years. Boys were likelier to be affected (1:1.3). In all age groups, falls and traffic accidents were the most common causes of thoracolumbar spine injuries. A total of 95 patients (62.1%) were treated conservatively, while 58 (37.9%) of the children underwent surgical treatment. Minimally invasive procedures were the most chosen procedures. Older children and adolescents were likelier to suffer from higher-grade injuries according to the AOSpine classification. The thoracolumbar junction (T11 to L2) was the most affected level along the thoracolumbar spine (n = 90). Neurological deficits were rarely seen in all age groups. Besides extremity injuries (n = 52, 30.2%), head injuries represented the most common accompanying injuries (n = 53, 30.8%). Regarding spinal injuries, most of the patients showed no evidence of complications during their hospital stay (96.7%). CONCLUSIONS The thoracolumbar junction was more frequently affected in older children and adolescents. The majority of thoracolumbar spinal column injuries were treated conservatively. Nevertheless, 37.9% of hospitalized children had to be treated surgically, and there was an acceptable complication rate for the surgeries that were performed.

Abstract
(1) Background: In elderly patients with type II odontoid fractures, accompanying severe atlantoaxial instability (AAI) is discussed as a marker possibly warranting more aggressive surgical therapy. This study aimed to characterize adverse events as well as the radiological and functional outcomes of surgical vs. conservative therapy in patients with odontoid fracture and AAI. (2) Methods: Patients aged 65 years and older with type II odontoid fracture and AAI treated were included. AAI was assumed if the mean subluxation across both atlantoaxial facet joints in the sagittal plane was greater than 50%. Data on demographics, comorbidities, treatment, adverse events, radiological, and functional outcomes were analyzed. (3) Results: Thirty-nine patients were included. Hospitalization time was significantly shorter in conservatively treated patients compared to patients with ventral or dorsal surgery. Adverse events occurred in 11 patients (28.2%), affecting 10 surgically treated patients (35.7%), and 1 conservatively treated patient (9.1%). Moreover, 25 patients were followed-up (64.1%). One secondary dislocation occurred in the conservative group (11.1%) and three in the surgical group (18.8%). (4) Conclusions: Despite the potential for instability in this injury, conservative treatment does not seem to lead to unfavorable short-term results, less adverse events, and a shorter hospital stay and should thus be considered and discussed with patients as a treatment option, even in the presence of severe AAI.

Abstract
PURPOSE To determine the incidence of severe surgical adverse events (sSAE) after surgery of patients with subaxial cervical spine injury (sCS-Fx) and to identify patient, treatment, and injury-related risk factors. METHODS Retrospective analysis of clinical and radiological data of sCS-Fx patients treated surgically between 2010 and 2020 at a single national trauma center. Baseline characteristics of demographic data, preexisting conditions, treatment, and injury morphology were extracted. Incidences of sSAEs within 60 days after surgery were analyzed. Univariate analysis and binary logistic regression for the occurrence of one or more sSAEs were performed to identify risk factors. P-values < .05 were considered statistically significant. RESULTS Two hundred and ninety-two patients were included. At least one sSAE occurred in 49 patients (16.8%). Most frequent were sSAEs of the surgical site (wound healing disorder, infection, etc.) affecting 29 patients (9.9%). Independent potential risk factors in logistic regression were higher age (OR 1.02 [1.003-1.04], p = .022), the presence of one or more modifiers in the AO Spine Subaxial Injury Classification (OR 2.02 [1.03-3.96], p = .041), and potentially unstable or unstable facet injury (OR 2.49 [1.24-4.99], p = .010). Other suspected risk factors were not statistically significant, among these Injury Severity Score, the need for surgery for concomitant injuries, the primary injury type according to AO Spine, and preexisting medical conditions. CONCLUSION sSAE rates after treatment of sCS-Fx are high. The identified risk factors are not perioperatively modifiable, but their knowledge should guide intra and postoperative care and surgical technique.

Abstract
INTRODUCTION This study analyzed the incidence of secondary dislocations (sDLs) after surgical stabilization of AO Spine type B and C injuries of the subaxial cervical spine (sCS). MATERIALS AND METHODS Patients treated for injuries of the sCS from 2010 to 2020 were retrospectively analyzed for the incidence of sDL within 60 days after first surgery. A univariate analysis of variables potentially influencing the risk of sDL was performed. Patients with solitary anterior stabilization underwent subgroup analysis. The treatment of sDLs was described. RESULTS A total of 275 patients were included. sDLs occurred in 4.0% of patients (n = 11) in the total sample, most frequently after solitary anterior stabilization with 8.0% (n = 10, p = 0.010). Only one sDL occurred after combined stabilization and no sDLs after posterior stabilization. In the total sample and the anterior subgroup, variables significantly associated with sDL were older age (p = 0.001) and concomitant unstable facet joint injury (p = 0.020). No neurological deterioration occurred due to sDL and most patients were treated with added posterior stabilization. sDL is frequent after solitary anterior stabilization and rare after posterior or combined stabilization. DISCUSSION Patients of higher age and with unstable facet joint injuries should be followed up diligently to detect sDLs in time. Neurological deterioration does not regularly occur due to sDL, and most patients can be treated with added posterior stabilization.

Abstract
BACKGROUND Different treatment options are discussed for geriatric odontoid fracture. The aim of this study was to compare the treatment options for geriatric odontoid fractures. METHODS Included were patients with the following criteria: age ≥ 65 years, identification of seniors at risk (ISAR score ≥ 2), and odontoid fracture type A/B according to Eysel and Roosen. Three groups were compared: conservative treatment, surgical therapy with ventral screw osteosynthesis or dorsal instrumentation. At a follow-up examination, the range of motion and the trabecular bone fracture healing rate were evaluated. Furthermore, demographic patient data, neurological status, length of stay at the hospital and at the intensive care unit (ICU) as well as the duration of surgery and occurring complications were analyzed. RESULTS A total of 72 patients were included and 43 patients could be re-examined (range: 2.7 ± 2.1 months). Patients with dorsal instrumentation had a better rotation. Other directions of motion were not significantly different. The trabecular bone fracture healing rate was 78.6%. The patients with dorsal instrumentation were hospitalized significantly longer; however, their duration at the ICU was shortest. There was no significant difference in complications. CONCLUSION Geriatric patients with odontoid fracture require individual treatment planning. Dorsal instrumentation may offer some advantages.

Abstract
STUDY DESIGN Mutlidisciplinary consensus recommendations for patients suffering from multiple myeloma (MM) involvement of the spinal column by the Spine Section of the German Association of Orthopaedic and Trauma Surgeons. OBJECTIVE To provide a comprehensive multidisciplinary diagnostic and therapeutic approach and to summarize the current literature on the management of pathological thoracolumbar vertebral fractures in patients with multiple myeloma. METHODS Multidisciplinary recommendations using a classical consensus process provided by radiation oncologists, medical oncologists, orthopaedic- and trauma surgeons. A narrative literature review of the current diagnostic and treatment strategies was conducted. RESULTS Treatment decision has to be driven by a multidisciplinary team of oncologists, radiotherapists and spine surgeons. When considering surgery in MM patients, differing factors compared to other secondary spinal lesions have to be included into the decision process: probable neurological deterioration, the stage of the disease and prognosis, patient's general condition, localization and number of the lesions as well as patient's own wishes or expectations. Aiming to improve quality of life, the major goal of surgical treatment is to preserve mobility by reducing pain, secure neurological function and stability. CONCLUSION The goal of surgery is primarily to improve quality of life by restoring stability and neurological function. Interventions with an increased risk of complications due to MM-associated immunodeficiency must be avoided whenever feasible to allow early systemic treatment. Hence, treatment decisions should be based on a multidisciplinary team that considers patient's constitution and prognosis.

Abstract
INTRODUCTION There are no evidence-based recommendations for the post-operative treatment and application of soft or rigid cervical collars after operative treatment of injuries of the subaxial cervical spine. Cervical collars can restrict peak range of motion and serve as a reminder to the patient. However, they can also cause pressure ulcers. The aim of this online-based survey among German spine centres was to gain an overview of post-operative treatment and the application of soft or rigid cervical collars after surgical treatment of injuries of the subaxial cervical spine. MATERIALS AND METHODS An online-based survey was conducted among 59 spine centres certified by the German Spine Society. It comprised seven items and the option of adding remarks in the form of open-ended responses. RESULTS The return rate was 63% (37 out of 59). Of the 37 analysed spine centres, 51% routinely apply a cervical collar post-operatively, 27% apply a soft and 16% a rigid cervical collar, 8% sequentially apply first a rigid and later a soft cervical collar. Less than half of the spine centres (43%) routinely use no cervical collar. Rigid collars are applied for more than 6 weeks and soft collars up to 6 weeks at some spine centres. Standardised post-operative treatment plans are common. The selection of the post-operative treatment plan depends primarily on the type of injury and method of operation and partly on patient age and bone quality. The satisfaction of German spine centres with the current handling of post-operative treatment of subaxial cervical spine injuries is high. DISCUSSION The post-operative treatment of injuries of the subaxial cervical spine at German spine centres is heterogeneous, and the evidence on advantages and disadvantages of the post-operative application of cervical collars is insufficient. Planning and implementation of randomised controlled clinical trials in subaxial cervical spine injuries is challenging.

Abstract
OBJECTIVES The purpose of this study was to (i) develop a protocol that supports decision making for prehospital spinal immobilization in pediatric trauma patients based on evidence from current scientific literature and (ii) perform an applicability test on emergency medicine personnel. METHODS A structured search of the literature published between 1980 and 2019 was performed in MEDLINE using PubMed. Based on this literature search, a new Emergency Medicine Spinal Immobilization Protocol for pediatric trauma patients (E.M.S. IMMO Protocol Pediatric) was developed. Parameters found in the literature, such as trauma mechanism and clinical findings that accounted for a high probability of spinal injury, were included in the protocol. An applicability test was administered to German emergency medicine personnel using a questionnaire with case examples to assess correct decision making according to the protocol. RESULTS The E.M.S. IMMO Protocol Pediatric was developed based on evidence from published literature. In the applicability test involving 44 emergency medicine providers revealed that 82.9% of participants chose the correct type of immobilization based on the protocol. A total of 97.8% evaluated the E.M.S. IMMO Protocol Pediatric as helpful. CONCLUSIONS Based on the current literature, the E.M.S. IMMO Protocol Pediatric was developed in accordance with established procedures used in trauma care. The decision regarding immobilization is made on based on the cardiopulmonary status of the patient, and life-threatening injuries are treated with priority. If the patient presents in stable condition, the necessity for full immobilization is assessed based upon the mechanisms of injury, assessment of impairment, and clinical examination.

Abstract
Background Along with the growing geriatric population, the number of odontoid fractures is steadily increasing. However, the effectiveness of immobilizing geriatric odontoid fractures using a cervical collar has been questioned. The aim of the present study is to analyze the physiological and pathological motion in odontoid fractures and to assess limitation of motion in the cervical spine when applying a cervical collar. Methods Motion analysis was performed with wireless motion tracker on unfixed geriatric human cadavers. First, a new geriatric type II odontoid fracture model was developed. In this model, the type II odontoid fracture is operated via a transoral approach. The physiological and pathological flexion and lateral bending of the cervical spine resulting from this procedure was measured. The resulting motion after external stabilization using a cervical collar was analyzed. Results The new geriatric type II odontoid fracture model was successfully established using seven unfixed human cadavers. The pathological flexion of the cervical spine was significantly increased compared to the physiological flexion (p = 0.027). Furthermore, the flexion was significantly reduced when a cervical collar was applied. In case of flexion the mean remaining motion was significantly reduced (p = 0.0017) from 41° to 14°. For lateral bending the mean remaining motion was significantly reduced (p = 0.0137) from 48° to 18°. Conclusions In case of type II odontoid fracture, flexion and lateral bending of the cervical spine are increased due to spinal instability. Thus, if an odontoid fracture is suspected in geriatric patients, the application of a cervical collar should always be considered since external stabilization can significantly reduce flexion and lateral bending.

Abstract
The aim of this study was to compare the remaining motion of an immobilized cervical spine using an innovative cervical collar as well as two traditional cervical collars. The study was performed on eight fresh human cadavers. The cervical spine was immobilized with one innovative (Lubo Airway Collar) and two traditional cervical collars (Stifneck and Perfit ACE). The flexion and lateral bending of the cervical spine were measured using a wireless motion tracker (Xsens). With the Weinman Lubo Airway Collar attached, the mean remaining flexion was 20.0 ± 9.0°. The mean remaining flexion was lowest with the Laerdal Stifneck (13.1 ± 6.6°) or Ambu Perfit ACE (10.8 ± 5.8°) applied. Compared to that of the innovative Weinmann Lubo Airway Collar, the remaining cervical spine flexion was significantly decreased with the Ambu Perfit ACE. There was no significant difference in lateral bending between the three examined collars. The most effective immobilization of the cervical spine was achieved when traditional cervical collars were implemented. However, all tested cervical collars showed remaining motion of the cervical spine. Thus, alternative immobilization techniques should be considered.

Abstract
BACKGROUND CONTEXT Patients' outcome following traumatic atlanto-occipital dislocation (AOD) has been poor. In recent years, an increasing number of patients surviving the initial trauma are admitted to hospital. In order to further improve the management of these patients, the knowledge of diagnostics and therapy as well as possible complications should be increased. PURRPOSE The aim of this study was to evaluate diagnostic parameters, therapy, early complications and outcome of patients with traumatic AOD. STUDY DESIGN Monocentric retrospective cohort study. PATIENT SAMPLE A total of 12 patients were included in this study. OUTCOME MEASURES The main outcome measure was functional patient outcome. Furthermore, radiographic and treatment data were analyzed. METHODS All patients suffering from traumatic AOD within an 8-year time period were included. Demographic data, radiological diagnostic parameters (condylar sum, basion dens interval, basion axis interval, power´s ratio, x-line method), as well as treatment data and complications of every patient were analyzed. Radiological parameters were compared with each other. Outcome was analyzed by a follow up examination. RESULTS The accident mechanisms were motor vehicle accidents (MVA), fall from high and low height. Basion dens interval, basion axis interval, power's ratio and x-line method were not reliable in identifying traumatic AOD (only up to 33% of the patients were identified). Twelve patients could be reviewed. Three patients were treated with surgery, five patients were treated nonsurgically. Four patients died before surgical therapy. All seven surviving patients (survival rate: 58.3%) were re-examined (mean follow-up time: 6.7 months). All patients had a GCS of 15. Three surviving patients suffered from persisting neurological deficits. CONCLUSIONS The most reliable way to diagnose AOD in Computer Topography is using the condylar sum. Surgical and nonsurgical measures can be employed with reasonable outcomes. Patient specific injury burden and clinical presentation should be taken into account when making treatment decisions for AOD.

Abstract
Introduction: Demographic changes have resulted in an increase in injuries among geriatric patients. For these patients, a rigid cervical collar is crucial for immobilizing the cervical spine. However, evidence suggests that patients with a geriatric facial structure require a different means of immobilization than patients with an adult facial structure. This study aimed to analyze the remaining motion of the immobilized cervical spine based on facial structure. Materials and Methods: This study was performed on 8 fresh human cadavers. Facial structure was evaluated via ascertaining the mandibular angle by computer tomography. A mandibular angle below 130°, belongs to the adult facial structure group (n = 4) and a mandibular angle above 130°, belongs to the geriatric facial structure group (n = 4). The flexion and lateral bending of the immobilized cervical spine were analyzed in both groups using a wireless motion tracker system. Results: A flexion of up to 19.0° was measured in the adult facial structure group. The mean flexion in the adult vs. geriatric facial structure groups were 14.5° vs. 6.5° (ranges: 9.0-19.0 vs. 5.0-7.0°), respectively. Thus, cervical spine motion was (p = 0.0286) significantly more reduced in the adult facial structure group. No (p = 0.0571) significant difference was oberserved in the mean lateral bending of the adult facial structure group (14.5°) compared to the geriatric facial structure group (7.5°). Conclusion: Emergency medical service personnel should therefore follow current guidelines and recommendations and perform cervical spine immobilization with a cervical collar, including in patients with a geriatric facial structure.

Abstract
PURPOSE For trauma surgeons, the evaluation of the stability of the upper cervical spine may be demanding. The aim of this study was to develop a protocol for decision-making on upper cervical spine stability in trauma patients based on established parameters obtained by CT imaging as well as testing the protocol by having it applied by trauma surgeons. METHODS A structured literature search on upper cervical spine stability was performed. The best evaluated instability criteria in CT imaging were determined. Based on these parameters a protocol for stability evaluation of the injured upper cervical spine was developed. A first application testing was performed. In addition to the assessment of instability, the time required for the assessment was analyzed. RESULTS A protocol for CT-based stability evaluation of the injured upper cervical spine based on the current literature was developed and displayed in a flow chart. Testing of the protocol found the stability of the cervical spine was correctly assessed in 55 of 56 evaluations (98.2%). In one test run, a stable upper cervical spine was judged to be unstable. Further analysis showed that this case was based on a measurement error. The assessment time of CT-images decreased significantly during repeat application of the protocol (p < 0.0001), from 336 ± 108 s (first case) to 180 ± 30 s (fourth case). CONCLUSION The protocol can be applied quickly and safely by non-specialized trauma surgeons. Thus, the protocol can support the decision-making process in CT-based evaluation of the stability of the injured upper cervical spine.

Abstract
BACKGROUND Spinal stabilization by an anterior vertebral body replacement is frequently used in patients suffering from destroyed vertebral bodies. The aim of this study was to analyse (i) the choice of endplate size and positioning of vertebral body replacements in daily patient care and (ii) if these factors have an influence on clinical and radiological outcomes. METHOD Patients' outcomes were analysed three years after vertebral body replacement implantation using the visual analogue scale spine score. Safe zones on the vertebral body endplates were defined. Overall endplate coverage and implant subsidence were evaluated by CT and X-ray. Compression tests were performed on 22 lumbar vertebral bodies to analyse endplates sizes' influence on subsidence. FINDING Mean coverage of the vertebral body's superior and inferior endplates by the vertebral body replacement was 27.8% and 30.8%, respectively. Mean overlap of the safe zone by the implant was 49.8% and 40.6%. Mean subsidence was 1.1 ± 1.2 mm, but it did not have any effect on the outcome. In the compression tests, no significant difference (p = 0.468) was found between the two endplate sizes. INTERPRETATION Coverage of vertebral body endplates and positioning of implants in the safe zone did not entirely comply with the given recommendations. The amount of endplate coverage had no influence on subsidence or long-term outcomes in daily patient care. On the other hand, correct positioning of the implant may influence its subsidence.

Abstract
PURPOSE This study aimed to identify the prevalence and predictors of spinal injuries that are suitable for immobilization. METHODS Retrospective cohort study drawing from the multi-center database of the TraumaRegister DGU®, spinal injury patients ≥ 16 years of age who scored ≥ 3 on the Abbreviated Injury Scale (AIS) between 2009 and 2016 were enrolled. RESULTS The mean age of the 145,833 patients enrolled was 52.7 ± 21.1 years. The hospital mortality rate was 13.9%, and the mean injury severity score (ISS) was 21.8 ± 11.8. Seventy percent of patients had no spine injury, 25.9% scored 2-3 on the AIS, and 4.1% scored 4-6 on the AIS. Among patients with isolated traumatic brain injury (TBI), 26.8% had spinal injuries with an AIS score of 4-6. Among patients with multi-system trauma and TBI, 44.7% had spinal injuries that scored 4-6 on the AIS. Regression analysis predicted a serious spine injury (SI; AIS 3-6) with a prevalence of 10.6% and cervical spine injury (CSI; AIS 3-6) with a prevalence of 5.1%. Blunt trauma was a predictor for SI and CSI (OR 4.066 and OR 3.640, respectively; both p < 0.001) and fall > 3 m for SI (OR 2.243; p < 0.001) but not CSI (OR 0.636; p < 0.001). Pre-hospital shock was predictive for SI and CSI (OR 1.87 and OR 2.342, respectively; both p < 0.001), and diminished or absent motor response was also predictive for SI (OR 3.171) and CSI (OR 7.462; both p < 0.001). Patients over 65 years of age were more frequently affected by CSI. CONCLUSIONS In addition to the clinical symptoms of pain, we identify '4S' [spill (fall) > 3 m, seniority (age > 65 years), seriously injured, skull/traumatic brain injury] as an indication for increased attention for CSIs or indication for spinal motion restriction.

Abstract
BACKGROUND Severe cervical spine injuries in children under the age of 17 years are rare. Recommendations or even guidelines for the diagnostics and treatment of such injuries in children are currently not available. OBJECTIVE The aim of the study was to formulate recommendations for diagnostics and treatment of injuries of the cervical spine in pediatric patients. MATERIAL AND METHODS First, a search of primary and secondary literature on the topic complex of diagnostics and treatment of cervical spine injuries in children was carried out. An appropriate internal literature database was defined and maintained. Second, within the framework of 9 meetings from April 2017 to December 2019 the members of the Pediatric Spinal Trauma Group of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU) systematically formulated recommendations for the diagnostics and treatment of injuries of the cervical spine in pediatric patients by a consensus process. RESULTS Recommendation for the diagnostics and treatment for injuries of the cervical spine could be formulated for three age groups (age group I: 0-6 years; age group II: 7-9 years; age group III: 10-16 years). The diagnostic and therapeutic principles known from adult patients suffering from injuries to the cervical spine cannot be easily transferred to pediatric patients. CONCLUSION Injuries to the pediatric spine are rare and should be treated in specialized spine centers. Pediatric patients with a stable cardiopulmonary status should undergo magnetic resonance imaging (MRI) if a spinal trauma is suspected. Classification systems and therapeutic recommendations for injuries to the cervical spine known from adult patients could also be used for adolescent patients. This is not possible for children under the age of 10 years. Only few classification systems exist for this age group. Basic principles of the treatment of spinal trauma in children is the restoration of spinal stability and correct anatomical relationships as well as the protection of all neural structures.

Abstract
BACKGROUND In general, pediatric spinal injuries are rare. No reliable data on the epidemiology of spinal injuries in pediatric patients in Germany are available. Especially in pediatric patients, for whom the medical history, clinical examination and the performance of imaging diagnostics are difficult to obtain, all available information on a spinal injury must be taken into account. OBJECTIVE The aim of this study was to provide epidemiological data for pediatric patients with spinal trauma in Germany in order to enhance future decision-making for the diagnostics and treatment of these patients. MATERIAL AND METHODS Within the framework of a national multicenter study, data were retrospectively obtained from 6 German spine centers for 7 years between January 2010 and December 2016. In addition to the demographic data, the clinical databases were screened for specific trauma mechanisms, level of injury as well as accompanying injuries. Furthermore, diagnostic imaging and the treatment selected were also analyzed. RESULTS A total of 367 children (female: male = 1:1.2) with a total of 610 spinal injuries were included in this study. The mean age was 12 years (±3.5 years). The most frequent trauma mechanisms were falls from <3 m and traffic accidents. The imaging diagnostics were only rarely carried out with the child under anesthesia. Younger children (0-9 years old) suffered more injuries to the cervical spine, whereas injuries to the thoracic and lumbar spine were more frequently found in older children (>10 years old). The children frequently showed accompanying injuries to the head and the extremities. Accompanying spinal injuries mostly occurred in adjacent regions and only rarely in other regions. Around 75% of the children were treated conservatively. CONCLUSION The results were different from the knowledge obtained from adult patients with spinal trauma and describe the special circumstances for pediatric patients with spinal trauma. Despite certain limitations these facts may help to enhance future decision-making for the diagnostics and treatment of these patients.

Abstract
BACKGROUND Spinal injuries in pediatric patients are overall very rare. Current reference studies including large patient numbers that enable the formulation of evidence-based recommendations on diagnostics and treatment of these injuries do not exist. OBJECTIVE The aim of the current study was to formulate recommendations on the diagnostics and treatment for injuries of the thoracic and lumbar spine in pediatric patients. MATERIAL AND METHODS Firstly, a search for primary and secondary literature on the topic of diagnostics and treatment of spinal injuries in children was carried out. From this, a literature database was established and maintained. Secondly, within the framework of 9 meetings in the time period from April 2017 to December 2019 the members of the Pediatric Spinal Trauma Group of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU) documented recommendations on diagnostics and treatment of injuries of the thoracic and lumbar spine in pediatric patients by a consensus process. RESULTS Recommendations on the diagnostics and treatment of injuries of the thoracic and lumbar spine could be given for 3 age groups (age group I: 0-6 years; age group II: 7-9 years; age group III: 10-16 years). Diagnostic and therapeutic principles known from adult patients suffering from injuries to the thoracic or lumbar spine cannot easily be transferred to pediatric patients. CONCLUSION Spinal injuries in childhood are rare and should be treated in specialized spine centers. Pediatric patients with a stable cardiopulmonary status should undergo magnetic resonance imaging (MRI) if a spinal trauma is suspected. The basic principles of the treatment of spinal trauma in children is the restoration of spinal stability and correct anatomical parameters as well as the protection of all neural structures. The potential for correction and regeneration of the individual spinal sections depending on the age of the patient must be considered for deciding between operative vs. conservative treatment. Whenever operative treatment is needed, it should be performed by minimally invasive techniques as a sole instrumentation without spondylodesis. An early removal of the screw-rod-system should be performed.

Abstract
BACKGROUND Spinal immobilization is a standard procedure in daily out-of-hospital emergency care. Homogenous recommendations concerning the immobilization of trauma patients during the first therapy in the emergency department do not exist. The aim of the current study was the analysis of the existing strategies concerning spinal immobilization in German level I trauma centers by an internet-based survey. MATERIALS AND METHODS The current study is a survey-based analysis of the current strategies concerning spinal immobilization in all 107 level I trauma centers in Germany. The internet-based survey consists of 6 items asking about immobilization in the emergency department. RESULTS The return rate was 47.7%. In 14 (28.6%) level I trauma centers the patients remained immobilized on the immobilization tool used by the professional emergency care providers. In 19 (38.8%) level I trauma centers the patients were transferred to a stretcher with a soft positioning mattress on it. Patient transfer to a spineboard or to a TraumaMattress was performed in 11 (22.4%) and 7 (14.3%) level I trauma centers, respectively. Trauma patients were never transferred to a vacuum mattress. Cervical spine protection was most of the time performed by a cervical collar (n = 48; 98.0%). In general, the survey's participants were mainly satisfied (mean = 84/100) with the current strategy of spinal immobilization. The satisfaction was best if the spineboard is used. DISCUSSION Patient positioning during initial emergency therapy in the emergency department of German level I trauma centers is highly heterogenous. Besides complete full body immobilization, also the lack of any immobilization was reported by the survey's participants.

Abstract
OBJECTIVE Dorsal stabilization is a frequently used procedure in the treatment of acute traumatic vertebral body fractures. Besides the traditional open surgical procedure, the percutaneous positioning of pedicle screws is now widely used. The aim of the current study is to compare pedicle screw misplacement following open vs. percutaneous dorsal instrumentation after traumatic spinal fracture of the thoracic and lumbar spine and to assess possible risk factors associated with pedicle screw misplacement. METHODS All patients who suffered a traumatic spinal fracture that were treated with dorsal stabilization in our level I trauma center in the period from 01/2007 to 03/2014 were included in this retrospective therapeutic cohort study. From 01/2007 to 06/2009, an open surgical procedure was used, and from 06/2009 to 03/2014, the percutaneous procedure was used for all types of fractures. Retrospectively, the positioning of every single pedicle screw was evaluated in the post-operative computed tomography scan and classified. Epidemiological data were also documented to compare the two treatment groups. RESULTS A total of 491 patients with 681 vertebral body fractures were included. Of 733 pedicle screws placed during the open surgery procedure, 96.0% were within the safe zone. There was no significant difference compared with pedicle screws placed percutaneously (95.3% of 1884 screws). In all other categories, the number of misplaced pedicle screws also showed no differences between the two treatment groups. There is a positive correlation between pedicle screw misplacement and duration of the operation. Most pedicle screws are misplaced at the levels T12, L1 and T7, T8. CONCLUSION The current study shows that percutaneous surgery using dorsal stabilization allows the positioning of pedicle screws in an equivalently safe manner compared with an open surgical procedure in the acute care of spinal trauma.

Abstract
BACKGROUND The application of cervical collars is a standard procedure in emergency care of trauma patients. It is often observed that the application of cervical collars is performed incorrectly, which may lead to reduced immobilization of the cervical spine. OBJECTIVES The objective of this study was to analyze the practical skills of professional emergency care providers concerning the application of cervical collars. MATERIALS AND METHODS Emergency care professionals (n = 104) were asked to apply a cervical collar to a training doll. Each performance step was assessed separately. Furthermore, personal and occupational data of all study participants were collected using a questionnaire. RESULTS The study participants included professional rescue personnel and emergency physicians. The average occupational experience of all study participants in out-of-hospital emergency care was 11.1 ± 8.9 years. Most participants had already received training on trauma care (61 %) and felt "very confident" in handling a cervical collar (84 %). The application of the cervical collar was performed correctly in 11 % of the performances. The most common error was incorrect size adjustment of the cervical collar (66 %). No association was found between the correct application of the cervical collar and possible parameters of influence, such as working experience in emergency care or participation in trauma courses. CONCLUSIONS Despite pronounced subjective confidence regarding the application of cervical collars, this study shows that there are general deficits in the practical skills of applying cervical collars. Therefore, a critical assessment of the current training contents on the subject of trauma care must be demanded.

Abstract
BACKGROUND In professional motorbike racing falls with high velocities are common. Nonetheless, severe injuries or deaths are rare when compared to regular road traffic. METHODS In this study, falls in all courses of the largest German race series IDM*Superbike between 2007 and 2013 were analyzed regarding injury patterns and hospital admissions. All races were accompanied by a medical team, including at least one physician who assessed every patient. RESULTS A total of 728 falls were included. A specific fall mechanism could be determined in 45.5% of the cases. 40.5% were admitted to a trauma center for further diagnostics. A definitive diagnosis was found in 45.4%. In most cases (29.9%) the injury pattern was a fracture of the extremities. In collisions a significantly higher odds ratio of 2.52 (P=0.0001) and in undetermined falls a significantly lower odds ratio of 0.47 (P<0.0001) was observed. CONCLUSIONS Fall patterns in professional motorbike racing do not significantly correlate with the severity of the injury. Thus, as in regular patient evaluation, each patient has to be examined thoroughly to avoid misinterpretation.

Abstract
PRIMARY OBJECTIVE We evaluated the neurologic, psychological and vegetative outcome, the health status and changes of the personal and occupational status of patients after traumatic brain injuries (TBIs). Correlations between outcome parameters and basic demographic factors and initial clinical status parameters of the patients were assessed. RESEARCH DESIGN Monocentric, retrospective follow-up analysis. METHODS AND PROCEDURES We evaluated the neurologic, psychological and vegetative outcome and health status of patients, who survived TBI with a mean follow-up time of 54 months. Glasgow Outcome Scale (GOS), Disability Rating Scale (DRS) and a questionnaire on Quality of Life were used for outcome measurement. The personal and occupational status, trauma-derived changes to that status and medical and demographic factors that have an impact on the health condition of patients after TBI were assessed. MAIN OUTCOMES AND RESULTS With a median GOS of 5.0 and median DRS of 3.0, our patients showed just moderate disabilities. Fifty-six per cent of the patients felt 'very good' or 'good'. Age, gender, the preclinical Glasgow Coma Scale (GCS), state of pupil reaction and surgical treatment did not seem to affect the GOS or DRS. Correlations between body mass index, age and gender and distinct neurologic, psychological and vegetative symptoms were found. The personal status did not change significantly after TBI. Changes to occupational and socioeconomic status were evident. CONCLUSIONS One-third of the patients are heavily affected by neurological, psychological and vegetative symptoms after surviving TBI. Some demographic factors affected this integrity.

Abstract
Background Unstable conditions of the craniocervical junction such as atlanto-occipital dislocation (AOD) or atlanto-axial instability (AAI) are severe injuries with a high risk of tetraplegia or death. Immobilization by a cervical collar to protect the patient from secondary damage is a standard procedure in trauma patients. If the application of a cervical collar to a patient with an unstable craniocervical condition may cause segmental motion and secondary injury to the spinal cord is unknown. The aim of the current study is (i) to analyze compression on the dural sac and (ii) to determine relative motion of the cervical spine during the procedure of applying a cervical collar in case of ligamentous unstable craniocervical junction. Methods and findings Ligamentous AOD as well as AOD combined with ligamentous AAI was simulated in two newly developed cadaveric trauma models. Compression of the dural sac and segmental angulation in the upper cervical spine were measured on video fluoroscopy after myelography during the application of a cervical collar. Furthermore, overall three-dimensional motion of the cervical spine was measured by a motion tracking system. In six cadavers each, the two new trauma models on AOD and AOD combined with AAI could be implemented. Mean dural sac compression was significantly increased to -1.1 mm (-1.3 to -0.7 mm) in case of AOD and -1.2 mm (-1.6 to -0.6 mm) in the combined model of AOD and AAI. Furthermore, there is a significant increased angulation at the C0/C1 level in the AOD model. Immense three-dimensional movement up to 22.9° of cervical spine flexion was documented during the procedure. Conclusion The current study pointed out that applying a cervical collar in general will cause immense three-dimensional movement. In case of unstable craniocervical junction, this leads to a dural sac compression and thus to possible damage to the spinal cord.

Abstract
INTRODUCTION Emergency management of upper cervical spine injuries often requires cervical spine immobilisation and some critical patients also require airway management. The movement of cervical spine created by tracheal intubation and cervical spine immobilisation can potentially exacerbate cervical spinal cord injury. However, the evidence that previous studies have provided remains unclear, due to lack of a direct measurement technique for dural sac's space during dynamic processes. Our study will use myelography method and a wireless human motion tracker to characterise and compare the change of dural sac's space during tracheal intubations and cervical spine immobilisation in the presence of unstable upper cervical spine injury such as atlanto-occipital dislocation or type II odontoid fracture. METHODS AND ANALYSIS Perform laryngoscopy and intubation, video laryngoscope intubation, laryngeal tube insertion, fiberoptic intubation and cervical collar application on cadaveric models of unstable upper cervical spine injury such as atlanto-occipital dislocation or type II odontoid fracture. The change of dural sac's space and the motion of unstable cervical segment are recorded by video fluoroscopy with previously performing myelography, which enables us to directly measure dural sac's space. Simultaneously, the whole cervical spine motion is recorded at a wireless human motion tracker. The maximum dural sac compression and the maximum angulation and distraction of the injured segment are measured by reviewing fluoroscopic and myelography images. ETHICS AND DISSEMINATION This study protocol has been approved by the Ethics Committee of the State Medical Association Rhineland-Palatinate, Mainz, Germany. The results will be published in relevant emergency journals and presented at relevant conferences. TRIAL REGISTRATION NUMBER DRKS00010499.

Abstract
BACKGROUND Around 5% of all trauma patients suffer from spinal trauma. Spinal fractures are mainly located in the thoracic and lumbar spine. For multisegmental vertebral fractures categorized as instable, combined dorsal instrumentation and ventral stabilization is recommended. Numerous vertebral body replacement systems are available for ventral stabilization. OBJECTIVES The aim of the current study was to analyze radiological results following the implantation of a hydraulic expandable vertebral body replacement and the evaluation of patients' outcome three years after implantation. MATERIALS AND METHODS All patients who suffered traumatic multisegmental fractures of the thoracic or lumbar spine in the period from September 2009 to September 2012 were included in this study. Patients with additional injuries or abnormal sensitivity or motor function were excluded from the current study. All patients underwent dorsal percutaneous instrumentation. Afterwards, implantation of the vertebral body replacement was performed via the mini-open approach at our level I trauma center. In the computed tomography and X‑ray imaging, the sagittal kyphotic angle was measured. Furthermore, the clinical outcome (patients' satisfaction, VAS spine score) was analyzed using a questionnaire. RESULTS During the above mentioned period, seven patients (four female; three male) underwent dorsal instrumentation and ventral trisegmental fusion and were identified fitting the inclusion/exclusion criteria and thus could be included in the study. Most fractures were located in the thoracic-lumbar junction and were categorized A4 according to the AO Spine classification system. The analysis of the radiological data showed a pre-operative average traumatic segmental angle of 18.1 ± 14.9°, which could be decreased by reposition procedure to 6.4 ± 1.7°. The complete follow-up, including the data three years after implantation of the vertebral body implant, was available for three patients. The traumatic segmental angle remained stable in the follow-up three years later. In one case, a subsidence of the implant of 1.5 mm was observed, having no influence on the patients' satisfaction. All three patients indicated to be very satisfied with their outcome. The VAS spine score rating was in the range between 62.4 and 70.2. CONCLUSIONS The current study shows that in the case of multisegmental fractures complete reposition by ligamentotaxis and by the percutaneous instrumentation system is possible. In addition to the percutaneous dorsal instrumentation, the implantation of a hydraulically expandable vertebral body replacement may allow a stable fusion after complex traumatic fractures of the thoracic and lumbar spine. Patients are very satisfied with their outcome after this procedure.

Abstract
Because spinal cord injuries can have fatal consequences for injured race car drivers, prehospital treatment of spinal injuries is a major concern in motor sports. A structured procedure for assessing trauma patients and their treatment should follow established ABCDE principles. Only then, a stable patient could be further examined and appropriate measures can be undertaken. For patients in an acute life-threatening condition, rapid transport must be initiated and should not be delayed by measures that are not indicated. If a competitor must first be extricated from the racing vehicle, the correct method of extrication must be chosen. To avoid secondary injury to the spine after a racing accident, in-line extrication from the vehicle and immobilization of the patient are standard procedures in motor sports and have been used for decades. Since immobilization can be associated with disadvantages and complications, the need for immobilization of trauma patients outside of motor sports medicine has become the subject of an increasing number of reports in the scientific literature. Even in motor sports, where specific safety systems that offer spinal protection are present, the indications for spinal immobilization need to be carefully considered rather than being blindly adopted as a matter of course. The aim of this article is to use recent literature to present an overview about the treatment of spinal injuries in motor sports. Further, we present a new protocol for indications for immobilizing the spine in motor sports that is based on the ABCDE principles and takes into account the condition of the patient.

Abstract
PURPOSE The aim of the current study is to analyze perioperative data and complications of open vs. percutaneous dorsal instrumentation after dorsal stabilization in patients suffering from fractures of the thoracic or lumbar spine. METHODS In the time period from 01/2007 to 06/2009, open surgical approach was used for dorsal stabilization. The percutaneous surgical approach was used from 05/2009 to 03/2014. In every time period, all types of fractures were treated only by open or by percutaneous approach, respectively, to avoid any selection bias. Retrospectively, epidemiological data, complications and perioperative data were documented and statistically analyzed. RESULTS A total of 491 patients met the inclusion criteria. Open surgery procedure was carried out on 169 patients, and percutaneous surgery procedure was carried out on 322 patients. Fracture level ranged from T1 to L5, and fractures were classified types A, B, and C. In 91.4% of all patients, no complication occured following dorsal stabilization after traumatic spine fracture during their hospital stay. However, 42 complications related to dorsal stabilization have been documented during the hospital stay. The complication rate was 14.8% if open surgical approach has been used and was significantly reduced to 5.3% using percutaneous surgical approach. Post-operative hospital stay was also reduced significantly using the percutaneous surgical approach. CONCLUSIONS According to the current study, percutaneous dorsal stabilization of the spine could also be safely used in trauma cases and is not restricted to degenerative spinal surgery.

Abstract
Introduction The Göttingen Minipig (GM) is used as large animal model in articular cartilage research. The aim of the study was to introduce osteoarthritis (OA) in the GM by resecting the anterior cruciate ligament (ACLR) according to Pond and Nuki, verified by histological and magnetic resonance imaging (MRI) scoring as well as analysis of gene and protein expression. Materials and Methods The eight included skeletally mature female GM were assessed after ACLR in the left and a sham operation in the right knee, which served as control. 26 weeks after surgery the knee joints were scanned using a 3-Tesla high-field MR tomography unit with a 3 T CP Large Flex Coil. Standard proton-density weighted fat saturated sequences in coronal and sagittal direction with a slice thickness of 3 mm were used. The MRI scans were assessed by two radiologists according to a modified WORMS-score, the X-rays of the knee joints by two evaluators. Osteochondral plugs with a diameter of 4mm were taken for histological examination from either the main loading zone or the macroscopic most degenerated parts of the tibia plateau or condyle respectively. The histological sections were blinded and scored by three experts according to Little et al. Gene expression analysis was performed from surrounding cartilage. Expression of adamts4, adamts5, acan, col1A1, col2, il-1ß, mmp1, mmp3, mmp13, vegf was determined by qRT-PCR. Immunohistochemical staining (IH) of Col I and II was performed. IH was scored using a 4 point grading (0—no staining; 3-intense staining). Results and Discussion Similar signs of OA were evident both in ACLR and sham operated knee joints with the histological scoring result of the ACLR joints with 6.48 ± 5.67 points and the sham joints with 6.86 ± 5.84 points (p = 0.7953) The MRI scoring yielded 0.34 ± 0.89 points for the ACLR and 0.03 ± 0.17 for the sham knee joints. There was no correlation between the histological and MRI scores (r = 0.10021). The gene expression profiles as well as the immunohistochemical findings showed no significant differences between ACLR and sham knee joints. In conclusion, both knee joints showed histological signs of OA after 26 weeks irrespective of whether the ACL was resected or not. As MRI results did not match the histological findings, MRI was obviously unsuitable to diagnose the OA in GM. The analysis of the expression patterns of the 10 genes could not shed light on the question, whether sham operation also induced cartilage erosion or if the degeneration was spontaneous. The modified Pond-Nuki model may be used with reservation in the adult minipig to induce an isolated osteoarthritis.

Abstract
BACKGROUND/OBJECTIVE The menisci of the mammalian knee joint balance the incongruence between femoral condyle and tibial plateau and thus menisci absorb and distribute high loads. Degeneration processes of the menisci lead to pain syndromes in the knee joint. The origin of such degenerative processes on meniscal tissue is rarely understood and may be described best as an imbalance of anabolic and catabolic metabolism. A standardized animal model of meniscal degeneration is needed for further studies. The aim of the current study was to develop a porcine animal model with early meniscal degeneration. MATERIAL AND METHODS Resection of the anterior cruciate ligament (ACLR) was performed on the left knee joints of eight Göttingen minipigs. A sham operation was carried out on the right knee joint. The grade of degeneration was determined 26 weeks after the operation using histology and magnetic resonance imaging (MRI). Furthermore, the expression of 14 genes which code for extracellular matrix proteins, catabolic matrix metalloproteinases and inflammation mediators were analyzed. RESULTS Degenerative changes were detected by a histological analysis of the medial meniscus after ACLR. These changes were not detected by MRI. In terms of their gene expression profile, these degenerated medial menisci showed a significantly increased expression of COL1A1. CONCLUSION This paper describes a new animal model for early secondary meniscal degeneration in the Göttingen minipig. Histopathological evidence of the degenerative changes could be described. This early degenerative changes could not be seen by NMR imaging.

Abstract
Background In order to match the challenges of quickly recognizing and treating any life-threatening injuries, the ABCDE principles were established for the assessment and treatment of trauma patients. The high priority of spine protection is emphasized by the fact that immobilization of the cervical spine is performed at the very first step in the ABCDE principles. Immobilization is typically performed to prevent or minimize secondary damage to the spinal cord if instability of the spinal column is suspected. Due to increasing reports about disadvantages of spinal immobilization, the indications for performing spinal immobilization must be refined. The aim of this study was (i) to develop a protocol that supports decision-making for spinal immobilization in adult trauma patients and (ii) to carry out the first applicability test by emergency medical personnel. Methods A structured literature search considering the literature from 1980 to 2014 was performed. Based on this literature and on the current guidelines, a new protocol that supports on scene decision-making for spinal immobilization has been developed. Parameters found in the literature concerning mechanisms and factors increasing the likelihood of spinal injury have been included in the new protocol. In order to test the applicability of the new protocol two surveys were performed on German emergency care providers by means of a questionnaire focused on correct decision-making if applying the protocol. Results Based on the current literature and guidelines, the Emergency Medicine Spinal Immobilization Protocol (E.M.S. IMMO Protocol) for adult trauma patients was developed. Following a fist applicability test involving 21 participants, the first version of the E.M.S. IMMO Protocol has to be graphically re-organized. A second applicability test comprised 50 participants with the current version of the protocol confirmed good applicability. Questions regarding immobilization of trauma patients could be answered properly using the E.M.S. IMMO Protocol. Discussion Current literature increasingly reports of disadvantages that may be associated with immobilization. Based on the requirements of the current guidelines, a new protocol that supports decision-making for indications for out-of-hospital spinal immobilization has been developed in this study. In contrast to established protocols, the new protocol offers different options for immobilization as well as a decicion-support. Conclusions The E.M.S. IMMO protocol provides a decision-support tool for indications for spinal immobilization in adult trauma patients that permits variable decision-making depending on the current condition of the trauma patient and the pattern of injuries for immobilization in general and for immobilization method in particular.

Abstract
The origin of the age-associated degenerative processes in meniscal tissue is poorly understood and may be related to an imbalance of anabolic and catabolic metabolism. The aim of the current study was to compare medial menisci isolated from juvenile pigs and degenerated medial menisci from adult pigs in terms of gene expression profile and ultrastructure. Medial menisci were isolated from the knee joints of juvenile and adult pigs (n = 8 for each group). Degeneration was determined histologically according to a scoring system. In addition, the gene expression profiles of 14 genes encoding extracellular matrix proteins, catabolic matrix metalloproteinases and mediators of inflammation were analyzed. Changes in the ultrastructure of the collagen network of the meniscal tissue were analyzed by using transmission electron microscopy. The histologic analysis of menisci showed significantly higher grade of degeneration in tissue isolated from adult porcine knee joints compared with menisci isolated from juvenile knee joints. In particular, destruction of the collagen network was greater in adult menisci than in juvenile menisci. Degenerated menisci showed significantly decreased gene expression of COL1A1 and increased expression of MMP2, MMP13, and IL8. The menisci from adult porcine knee joints can serve as a model for meniscal degeneration. Degenerative changes were manifested as differences in histopathology, gene expression and ultrastructure of collagen network.

Abstract
Background/Objective The application of a cervical collar is a standard procedure in trauma patients in emergency medicine. It is often observed that cervical collars are applied incorrectly, resulting in reduced immobilization of the cervical spine. The objective of this study was to analyze the practical skills of trained professional rescue personnel concerning the application of cervical collars. Material and Methods Within emergency medical conferences, n = 104 voluntary test subjects were asked to apply a cervical collar to a training doll, wherein each step that was performed received an evaluation. Furthermore, personal and occupational data of all study participants were collected using a questionnaire. Results The test subjects included professional rescue personnel (80.8%) and emergency physicians (12.5%). The average occupational experience of all study participants in pre-clinical emergency care was 11.1±8.9 years. Most study participants had already attended a certified training on trauma care (61%) and felt "very confident" in handling a cervical collar (84%). 11% applied the cervical collar to the training doll without errors. The most common error consisted of incorrect adjustment of the size of the cervical collar (66%). No association was found between the correct application of the cervical collar and the occupational group of the test subjects (trained rescue personnel vs. emergency physicians) or the participation in certified trauma courses. Conclusion Despite pronounced subjective confidence regarding the application of cervical collars, this study allows the conclusion that there are general deficits in practical skills when cervical collars are applied. A critical assessment of the current training contents on the subject of trauma care must, therefore, be demanded.

Abstract
In recent years, the emergency medical services in Wiesbaden and the Rheingau-Taunus district made great efforts to standardise structures. Since there are only few established procedures in the annual examinations for paramedics, there is reason to assume that treatment procedures for patients have not been standardised either. Materials and equipment are not handled uniformly, and employee satisfaction has significantly decreased over the last few years. To solve these problems, all paramedics undergo standardised and structured trainings. These training courses make use of the internationally accepted PHTLS (Pre-Hospital Trauma Life Support) and AMLS (Advanced Life Support Medial) programmes. In addition, practising skills and handling the equipment as well as on-scene supervision is to be established in practical training sessions.

Abstract
In this study, mapping of ultrashort T2 and T2* of acutely isolated porcine menisci at B0 = 9.4 T was investigated. Maps of T2 were measured from a slice through the pars intermedia with a spin echo-prepared two-dimensional ultrashort-TE T2 mapping technique published previously. T2* mapping was performed by two-dimensional ultrashort-TE MRI with variable acquisition delay. The measured signal decays were fitted by monoexponential, biexponential and Gaussian-exponential fitting functions. The occurrence of Gaussian-like signal decays is outlined theoretically. The quality of the curve fits was visualized by mapping the value δ = abs(1 - χ(2) red). For T2 mapping, the Gaussian-exponential fit showed the best performance, whereas the monoexponential and biexponential fits showed regionally high values of δ (δ > 20). Interpretation of the Gaussian-exponential parameter maps was found to be difficult, because a Gaussian signal component can be related to mesoscopic (collagen texture) or macroscopic (slice profile, shim, sample geometry) magnetic field inhomogeneities and/or residual (1) H dipole-dipole couplings. It seems likely that an interplay of these effects yielded the observed signal decays. Modulation of the T2* signal decay caused by chemical shift was observed and addressed to fat protons by means of histology. In the T2 measurements, no modulation of the signal decay was observed and the biexponential and Gaussian-exponential fits showed the best performance with comparable values of δ. Our results suggest that T2 mapping provides the more robust method for the characterization of meniscal tissue by means of MRI relaxometry. However, mapping of ultrashort T2, as performed in this study, is time consuming and provides less signal-to-noise ratio per time than the mapping of T2*. If T2* mapping is used, pixel-wise monitoring of the fitting quality based on reduced χ(2) should be employed and great care should be taken when interpreting the parameter maps of the fits.

Abstract
Spontaneous activity occurs in the mammalian auditory system prior to hearing onset and is relevant for neuronal differentiation. Growing evidence indicates that miniature events, i.e., action potential-independent synaptic activity, also have some developmental relevance. An intriguing question is whether these events are purely stochastic or rather display specific characteristics. We addressed this question and studied miniature excitatory postsynaptic currents (mEPSCs) in morphologically defined neurons of the rat lateral superior olive (LSO) during early neonatal life. To do so, whole-cell recordings from neurons in acute slices were combined with Lucifer yellow fillings. mEPSCs were identified by their TTX insensitivity and their blockade by glutamate receptor antagonists. Altogether, 60% of the LSO neurons displayed mEPSCs, and their presence correlated with the cell location and morphology. Their percentage was highest in the medial limb (86%) and lowest in the lateral limb (14%). Seventy-seven percent of the neurons with mEPSCs were bipolar cells, whereas 77% of those without mEPSCs were multipolar cells. The neuromodulator ATP affected the frequency of mEPSCs in 61% of the LSO neurons in a heterogeneous manner: both frequency increases and decreases occurred. These data provide further evidence for the specificity of mEPSCs. Finally, we investigated whether missing cochlear input changes mEPSCs characteristics. Characterizing LSO neurons of Ca(V)1.3(-/-) mice, which lack cochlea-driven nerve activity, we observed higher mEPSC frequencies and peak amplitudes, indicative of a compensatory response to deprivation. Together, our results demonstrate specific, rather than stochastic, characteristics of mEPSCs in the neonatal LSO, in accordance with their potential developmental significance.
